Guide to STN Patent Databases
Often it is necessary to use a document kind code together with a patent number, e.g. in legal status searches, or to
restrict the scope of the search to certain types of documents in a subject or SDI search strategy. To do this, the
publication kind codes must be entered in this format:
CCnn
CC Country (Two-letter code)
n Optional, letter, digit, or space
In some databases (e.g. INPADOCDB, INPAFAMDB, PATDPA) the meaning of the PK entry can be seen in the PIT
(patent information type) field:
=> E EPA/PK 6
E1 662 EEU1/PK
E2 10368 EGA/PK
E3 483 --> EPA/PK
E4 1163265 EPA1/PK
E5 640691 EPA2/PK
E6 468255 EPA3/PK
=> E EPA/PIT 6
E1 9 EEU1 REGISTERED UTILITY MODEL/PIT
E2 10368 EGA PATENT FOR INVENTION / PATENT OF ADDITION/PIT
E3 0 --> EPA/PIT
E4 1163265 EPA1 APPLICATION PUBLISHED WITH SEARCH REPORT/PIT
E5 640691 EPA2 APPLICATION PUBLISHED WITHOUT SEARCH REPORT/PIT
E6 468255 EPA3 SEARCH REPORT/PIT
In the STN patent databases the so-called DOCDB coding is now used.
